Naomi Osaka said she will remain a fan of Serena Williams who is chasing a record-equalling 24th major, just a year after giving birth and undergoing four post-natal surgeries.

Naomi Osaka told US Open title opponent Serena Williams "I love you" just moments after she became the first Japanese woman to reach a Grand Slam final. The 20-year-old breakout star of the tournament swept into the record books and Saturday's championship match against the 23-time major winner with a 6-2, 6-4 win over Madison Keys, the runner-up in 2017. When asked on court what she told herself as she served for the match, she said: "Don't double fault". "Why," asked the interviewer. "Serena," replied the charismatic Osaka.
